Supporting shape reinterpretation with eye tracking

It has been argued that reinterpretation is an essential process in design generation and idea exploration. However, computational design tools, such as computer-aided design systems, offer poor support for shape reinterpretation, and as such are not well suited to ideation in conceptual design. One of the key difficulties in implementing computational systems that support shape reinterpretation is the issue of interface – how can a user intuitively guide a system with respect to their interpretation of a designed shape? In this paper, a software prototype is presented that uses an eye tracking interface to support reinterpretation of shapes according to recognised subshapes. The prototype is based on eye tracking studies, and uses gaze data and user input to restructure designed shapes so that they afford manipulation according to users’ interpretations

On curves and computation with shapes

Few computer implementations of shape grammars have been written that are applicable to curved shapes. The reason for this is that underlying representations of curves do not lend themselves to providing a unique description of curved shapes. Such a representation is essential for shape algorithms. This paper explains the problems posed in representing curves for shape grammar implementation. The paper demonstrates how the fundamental structures for implementing shape grammars for straight lines can be extended to shapes with curved elements

Design synthesis and shape generation

If we are to capitalise on the potential that a design approach might bring to innovation in business and society, we need to build a better understanding of the evolving skill-sets that designers will need and the contexts within which design might operate. This demands more discourse between those involved in cutting edge practice, the researchers who help to uncover principles, codify knowledge and create theories and the educators who are nurturing future design talent. This book promotes such a discourse by reporting on the work of twenty research teams who explored different facets of future design activity as part of Phase 2 of the UK's research council supported Designing for the 21st Century Research Initiative. Each of these contributions describes the origins of the project, the research team and their project aims, the research methods used and the new knowledge and understanding generated. Editor and Initiative Director, Professor Tom Inns, provides an introductory chapter that suggests ways the reader might navigate these viewpoints. This chapter concludes with an overview of the key lessons that might be learnt from this collection of design research activity

Real-time automated failure identification in the Control Center Complex (CCC)

A system which will provide real-time failure management support to the Space Station Freedom program is described. The system's use of a simplified form of model based reasoning qualifies it as an advanced automation system. However, it differs from most such systems in that it was designed from the outset to meet two sets of requirements. First, it must provide a useful increment to the fault management capabilities of the Johnson Space Center (JSC) Control Center Complex (CCC) Fault Detection Management system. Second, it must satisfy CCC operational environment constraints such as cost, computer resource requirements, verification, and validation, etc. The need to meet both requirement sets presents a much greater design challenge than would have been the case had functionality been the sole design consideration. The choice of technology, discussing aspects of that choice and the process for migrating it into the control center is overviewed

Design exploration with useless rules and eye tracking

Shape reinterpretation is an essential component in design generation and exploration. However, computational design tools, such as computer-aided design systems, offer poor support for shape reinterpretation and, as a result, do not provide effective support for design ideation. A key difficulty in realising systems that support shape reinterpretation is the issue of interface – how can a user guide a system with respect to their interpretations of a shape? In this paper, research is presented that explores this question through the development of a software prototype. The prototype uses identity shape rules (so-called ‘useless rules’) and eye tracking to support the creation and manipulation of shapes. The paper presents theoretical developments that have informed development of the prototype, including outcomes of a series of eye tracking studies. The software prototype builds on the results from these studies and uses gaze data in combination with traditional mouse-based input to restructure designed shapes based on the visual attention of the users, so that manipulation according to the users’ interpretations is afforded

Comparing DSM-5-hybrid, SWAP, and PDM prototype models of personality disorders: Convergent and divergent findings

Although dimensional models of personality disorders are of great interest, there exist three methods by which personality disorders may be diagnosed for their fit to a predetermined prototype. In this study, we evaluate a Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), hybrid model prototype match (modified from the original prototype DSM-5 proposal; Skodol, Bender, Morey, et al., 2011; Skodol, Bender, Oldham, et al., 2011), the Shedler-Westen Assessment Procedure-2 (Shedler, 2015), and the Psychodynamic Diagnostic Manual prototype match (PDM Task Force, 2006). Three hundred twenty-nine clinical psychology graduate students and interns rated patients they currently were treating with each of the aforementioned diagnostic models, as well as completing a checklist of their DSM-IV personality disorder symptoms. Matching a prototype was defined as being a very good match (exemplifying the disorder, a prototypical case) or a good match (has the diagnosis, disorder applies). Frequencies of the prototype assignments are reported. For the SWAP-2 and PDM, depressive and borderline personality disorders were most frequently assigned, whereas avoidant and borderline personality disorder were the most assigned prototypes for the DSM-5 hybrid categories. However, the degree of convergence across methods on similar diagnostic constructs was low. Implications of these findings for personality disorder diagnosis are discussed
